Someone is making this harder and harder. To prove this, there are 7 doors. Each door has its own clue and they're all true. The colours of the doors are:
Red, Green, Blue, Yellow, Purple, Orange, and Brown.

THE CLUES

Red door's clue: This door is in the middle. It's three spots away from the door to freedom.

Green door's clue: This door is three spaces from the colour made by mixing red and blue. It's farther left than the red door.

Blue door's clue: This door is directly right of the purple door.

Yellow door's clue: This door is farther right than the red door but left of the purple door.
